Race strategy

Run hard on the first mountain, but save energy for the second.

  • Big early climb with 1400m gain. Hold your pace, save your legs for later.
  • 1212m descent. Go easy, save your quads.
  • The finish is runnable. Save your legs to run it all the way.
  • Long race. Control your HR and effort. Early mistakes cost the most.
  • Control your HR on the first mountain, save your quads on the descents until 47.2km, then run your race pace.
  • Start · 0.0km–1.9km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 1.9km–17.0km · Climb of 1398m. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace. At altitude your pace drops, and that's fine. Hike the steepest pitches.
  • Work · 17.0km–34.4km · Descent of 1212m averaging 11%, climb of 1002m, high point 2697m. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace. This descent is hard on the legs: short steps, stay in control, poles if you have them. At altitude your pace drops, and that's fine. Hike the steepest pitches.
  • Fade · 34.4km–67.4km · Descent of 1535m averaging 12%. Plus 1 more descent. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. This descent is hard on the legs: short steps, stay in control, poles if you have them. Running pays off here: run wherever you can. At altitude your pace drops, and that's fine. Hike the steepest pitches. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
  • Home · 67.4km–75.3km · 7.9km of runnable trail. No heroics: settle back into your own effort and hold it to the line. Running pays off here: run wherever you can.
